1. This can be done by the completely unconditional and radical forgiveness and acceptance of absolutely EVERYTHING, as it is right now in this very moment, always. This is the path of nonjudgemental acceptance, forgiveness, Love, compassion, and selflessness. If there's full blown acceptance of absolutely everything as it is, then there's nothing to judge, nothing to describe, nothing to define, nothing to talk about, nothing to express an opinion about, no thing to make into something, nothing to express a belief about, nothing to search for, nothing to manipulate, nothing to change, nothing to force, and there's nothing to think about at all. Everything just IS, nothing more, and one sees the absolute perfection and beauty in everything because everything and everyone is currently operating at it's own level of awareness and/or evolution. Everyone and everything is what it is right now because that's what it needs to learn, or un-learn. They REALLY DON"T know otherwise, or they don't want to know otherwise. If they REALLY knew otherwise, they would be otherwise.
2. Enlightenment can also happen by way of wisdom/Truth/mindfulness/Awareness, which involves non-effort, loss of interest in all thinking and thoughts, and letting go constantly and continuously. Watching the mind does not mean concentration or effort because concentrating is something that the ego/mind does. Nothing can be forced to happen, as force is the nature of the ego/mind. As soon as you watch thoughts, they dissapear. If you try to fight thoughts, you give them more strength because focus and energy is being put into fighting and conflict, which is again, a thing of the mind.
